Hey all, at the suggestion of others, I'm posting a photo of an ammonite fossil for assistance on species. This ammonite was unearthed by my father in 1972 in Shasta County CA. It measures 25 1/2 inches long by 20 inches tall. Any suggestions and help with its species and rarity is greatly appreciated. I get that it is not a complete specimen but hoping someone can help, Shannon

My daughter found this really cool fossil yesterday on Bolinas Lagoon. Any clues as to what it could be? We find lots of sand dollar fossils around here but this looks more like a bone from a large animal. It's about two inches in length & an inch wide. Very heavy.

Interesting little 'rocks' from today. 2 may be nothing, 2 I'm pretty sure about, and 2, seem to be imprints. Hope you guys can tell me. Again, Half Moon Bay. Also, how do I clean these?
-
Found this on the same beach as the others, a chunk of cliff had recently fallen away, I assume that's why I found some, and am wondering if there might be more now ...
-
-
I think this is a bivalve. I'm curious as to whether or not I'm right, and what it's age might be.
-
My daughter insisted I bring this home, and I wondered if it's a fossil or just an interesting rock.
-
Found this in Southern California, the rocks are either Paleozoic or Mesozoic, I'm really unsure but this was near the Silverado area. What do you think?
-
Can you please help us identify it?

New Pleistocene Vertebrate Fossils from Los Angeles, California, Subway Excavations
Oxytropidoceras posted a topic in Fossil News
Ice Age fossils emerge during Los Angeles subway dig Diana Kruzman , USA Today, July 10, 2017 https://www.usatoday.com/story/news/2017/07/10/ice-age-fossils-emerge-los-angeles-subway-dig/103026368/ Yours, Paul H. -
I've recently started having an interest in Paleozoic fossils simply because I've never actually found any. I live in southern California and recently went near the area of Corona to check out some of the paleozoic rocks. Unfortunately all seemed to be highly meta-morphed with hardly any trace of fossils, if any. So my question is, how do I go about finding paleozoic material in southern California? Are the metamorphed rocks hopeless? Thanks in advance
-
so I found a lot of cool things I just want to know what you guys think? Can you confirm what this stuff is? And maybe how old it is? You guys inspire me to keep looking!

Hi! I'm new to scene and have only just begun to expand my knowledge in fossils. Having said that, I'm open to any suggestions, knowledge, education, methods, etc. as to how to figure what this specimen is! Thanks for your time, much appreciated. I found this about a 1/4 mile off the coastline in a seasonal drainage in Northern California. Ohhh FYI my scale is set in grams

Greetings everyone! I am a long time follower of this site. This is my first posting. Thanks ahead of time for any assistance in identifying the following. I recently found a fossilized bone and what looks like a fossilized organ or concretion. I am usually pretty good about recognizing a concretion when I see one. However, this one looks a lot different from the concretions I normally come across in the area. They were both found within several feet of each other in an alluvium/terrace deposit. R. Squires describes the alluvium as "nonmarine, Holocene, last 10,000 years" and the terrace deposit as "nonmarine, upper Pleistocene, 50,000 to 10,000 years." The location is immediately adjacent to the Santa Susana Formation (marine, upper Paleocene to lower Eocene, 54 to 50 million years) and the Simi Conglomerate (nonmarine to marine, lower Paleocene, 65 million years). There are several other formations in the general vicinity of this location. I have several pictures of both (see below). The first set (F1) are of the bone, the second set (F2) is of the possible organ/concretion.

Here is a fossil I found from the Miocene in Southern California. The rocks should be marine. Any idea what it could be? Thanks in advance

Found this when i was a kid bit have never knownwhat kind of tooth it was. Can anyone help ID it?
-
I am new to fossils... I found this on the rocky shore of Cabrillo Beach, San Pedro, California. The rock is a hard sandstone. Any idea about the fossils?

Went fossil collecting in Bakersfield Round mountain silt formation this weekend and found an unusual tooth. I think it belongs to a mako shark (isurus planus), but it is unlike any other shark tooth I have ever found from the locality. The root is damaged, but it is more than twice as thick as any other hook mako I have ever found. Never seen a shark tooth this thick. Any ideas on the identity of this tooth? Thanks in advance for the help.

OK, I finally took a camera with me on this one. For the past year, I have visited an area about an hour south of me that is a source for Great White teeth and other marine animal parts. But for the most part, GW teeth is the majority of what is found. Now the location is perched on a steep hillside about 7 miles inland of the Pacific Ocean. It was a deposit that had been cut through by a river and re-deposited in a different location, much like many of the sites along the east coast are now. However, the redeposition was done a very long time ago. It is found about 200 feet above the valley floor and goes up at an angle due to faulting (what else would you expect in California, the land of earthquakes?) The formation consists of what I can easily call cemented gravel (heavy emphasis on the cement part!) I only have a hand pick and a trench trowel (folding shovel) to somehow work my way through that "rock". It doesn't take long swinging a pick with one hand to wear you out. By the end of the day, My arm feels like limp spaghetti. Because this ground is so hard and worked by river action, finding a whole tooth with roots intact is something of a rarity. Mostly you will find shards of crown enamel or the teeth are so worn they have no serrations at all. I had worked a hole for a while only to figure out the actual deposit was about 12" below the floor of my pit. Did I mention the deposit goes up at an angle? Missed it!!!! OH MAN! I had to backtrack removing my tailing pile and having to re dig the hole to a lower level. Did I mention the humidity was about 105%? I was completely drenched in sweat. Nobody said fossil hunting was easy work!!!! The first photos are the small hole I had to dig to establish the fossil layer once the tailings were removed. Believe me that ground is much harder than it looks. Guess I can skip the gym this week! Last photo is the day's tally. All Great Whites except for a small Cow Shark tooth. The top tooth on the left is 2 1/8" there is a small tooth in matrix at the bottom (note there is no root). I was lucky enough to get three with whole roots this trip. Thank you for putting up with my rabbling. Doren/ caldigger

First off, I want to thank Doren for sending me a small flat rate box full of STH matrix for me to try sifting through. I still have quite a bit of fine matrix to sort through but already I've managed to find hundreds of specimens. I've found quite a few Carcharhinus, Cetorhinus, Galeorhinus, Squalus, and tons of ray teeth. When I'm finished with all the matrix, I think I'll write a follow-up post with all the nice specimens I found. I'm having a little trouble identifying various species of rays - maybe someone has a literature suggestion to help me get familiar with different tooth characteristics? From what I can tell from other posts, the features that differentiate some ray species are quite subtle and to my untrained eye, very difficult to distinguish. I wouldn't mind some ID help with these teeth in particular. Scale to the right is in mm. If you could also comment on how common/uncommon these species are and what position they are in the jaw that would be immensely helpful as well. Also, maybe someone wouldn't mind making a list of the species found at STH and rank how common they are? Also, does anyone have suggestions for removing the last bit of silt/sand from the crevices in the teeth? I've tried water and gently stirring but that does not have much of an effect. Thanks for your help!
